There is one person who sends me three cards every year. One on New Year's, one for my birthday and the third that marks the anniversary of my flight into space.

If you end up doing what you are passionate about, the journey is so easy.

Watching sunrise and sunset from space, which is a beautiful sight, has been a personal privilege I have attained while being there. Another reflection from within I felt was that there was nothing which was neither visible and nor with a supportive environment as to how Planet Earth is.

Space exploration has taken a tremendous technological leap. India as a developing nation has been recognized globally for how it has economized its missions, which have been comparatively low-cost compared with other countries.

Anyone who goes to space tried to look at his own country first, but soon it appears that there is no boundary between the countries and the entire world is one family where our destinies are integrated.

Yes, we have ruined the Earth and have done an exceptionally good job of it. Yes, we should look at sustainable development. But we cannot afford to do things sequentially, but parallelly and make sure that we do not repeat our mistakes.
